WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Please observe all WARNINGS and “Service Precautions” under “On-
Vehicle Service” in air bag system section before performing service on or around the air bag sys-
tem components or wiring. Failure to follow WARNINGS could result in unintentional activation of
the system or could render the system inoperative. Either of these two conditions may result in
severe injury.
The procedures in this section must be followed in the order listed to temporarily disable the air
bag system and prevent false diagnostic codes from setting. Failure to follow procedures could
result in possible air bag system activation, personal injury or otherwise unneeded air bag system
repairs.
CAUTION:
When fasteners are removed, always reinstall them at the same location from which they were
removed. If a fastener needs to be replaced, use the correct part number fastener for that application.
If the correct part number fastener is not available, a fastener of equal size and strength (or stronger)
may be used. Fasteners that are not reused, and those requiring thread-locking compound, will be
called out. The correct torque value must be used when installing fasteners that require it. If the above
procedures are not followed, parts or system damage could result.

3C-2 STEERING WHEEL AND COLUMN
GENERAL DESCRIPTION
STEERING COLUMN
This double tube type steering column has following three important features in addition to the steering function
:
The column is energy absorbing, designed to compress in a front-end collision.
The ignition switch and lock are mounted conveniently on this column.
With the column mounted lock, the ignition and steering operations can be locked to inhibit theft of the vehi-
cle.
To insure the energy absorbing action, it is important that only the specified screws, bolts, and nuts be used as
designated and that they are tightened to the specified torque.
When the column assembly is removed from the vehicle, special care must be taken in handling it. Use of a
steering wheel puller other than the one recommended in this manual or a sharp blow on the end of the steering
shaft, leaning on the assembly, or dropping the assembly could shear the plastic shear pins which maintain col-
umn length and position.
STEERING WHEEL AND DRIVER AIR BAG (INFLATOR) MODULE
The driver air bag (inflator) module is one of the supplemental restraint (air bag) system components and is
mounted to the center of the steering wheel. During certain frontal crashes, the air bag system supplements the
restraint of the driver’s and passenger’s seat belts by deploying the air bags.
The air bag (inflator) module should be handled with care to prevent accidental deployment. When servicing, be
sure to observe all WARNINGS and CAUTIONS and “SERVICE PRECAUTIONS” under “ON-VEHICLE SER-
VICE” in Section 10B.
DIAGNOSIS
For maintenance service of the steering wheel and column, refer to Section 0B.
For diagnosis of the steering wheel and column, refer to Section 3.
For diagnosis of the air bag system, refer to Section 10B.
INSPECTION AND REPAIR REQUIRED AFTER ACCIDENT
After an accident, whether the air bag has been deployed or not, be sure to perform checks, inspections and
repairs described under “CHECKING STEERING COLUMN ASSEMBLY AND LOWER SHAFT FOR ACCI-
DENT DAMAGE” as well as “REPAIRS AND INSPECTIONS REQUIRED AFTER ACCIDENT” under “DIAGNO-
SIS” in Section 10B.

HANDLING AND STORAGE
For handling and storage, refer to “HANDLING AND STORAGE” under “SERVICE PRECAUTIONS” in Section
10B.
DISPOSAL
For disposal, refer to “DISPOSAL” under “SERVICE PRECAUTIONS” in Section 10B.
DRIVER AIR BAG (INFLATOR) MODULE
REMOVAL
1) Disconnect negative cable at battery.
2) Disable air bag system. Refer to “DISABLING AIR BAG
SYSTEM” under “SERVICE PRECAUTIONS” in Section
10B.
3) Loosen 2 bolts (1) mounting driver air bag (inflator) module
on its both side.
4) Remove driver air bag (inflator) module (3) from steering
wheel.
5) Disconnect yellow connector (1) of driver air bag (inflator)
module and horn connector (2) in order a) – d) shown in fig-
ure. WARNING:
When handling an air bag (inflator) module, be sure to
read “SERVICE PRECAUTIONS” in Section 10B and
observe each instruction. Failure to follow them could
cause a damage to the air bag (inflator) module or result
in personal injury.

STEERING WHEEL AND COLUMN 3C-5
INSPECTION
Check air bag (inflator) module visually and if any of the following
is found, replace it with a new one.
Air bag being deployed
Trim cover (pad surface) (1) being cracked
Wire harness or connector (2) being damaged
Air bag (inflator) module being damaged or having been
exposed to strong impact (dropped)
INSTALLATION
1) Check that horn wire is connected to horn connector (2)
securely.
2) Connect yellow connector (1) of driver air bag (inflator) mod-
ule (3) and horn connector in order a) – d) shown in figure
securely.
3) Install driver air bag (inflator) module to steering wheel, tak-
ing care so that no part of wire harness is caught between
them.
4) Make sure that clearance between module and steering
wheel is uniform all the way.
5) Tighten driver air bag (inflator) module mounting bolts (1) to
specified torque.
Tightening torque
Driver air bag (inflator) module mounting bolt
(a) : 9 N·m (0.9 kg-m, 6.5 lb-ft)
6) Connect negative cable at battery.
7) Enable air bag system. Refer to “ENABLING AIR BAG SYS-
TEM” under “SERVICE PRECAUTIONS” in Section 10B. WARNING:
Never disassemble driver air bag (inflator) module or
measure its resistance. Otherwise, personal injury may
result.
CAUTION:
If air bag (inflator) module was dropped from a height of
90 cm (3 ft) or more, it should be replaced.

3C-6 STEERING WHEEL AND COLUMN
STEERING WHEEL
REMOVAL
1) Remove driver air bag (inflator) module from steering wheel.
Refer to “DRIVER AIR BAG (INFLATOR) MODULE”.
2) Remove steering shaft nut.
3) Make alignment marks (1) on steering wheel and shaft for a
guide during reinstallation.
4) Remove steering wheel (1) with special tool.
Special tool
(A) : 09944-36011 CAUTION:
Removal of the steering wheel allows the contact coil to
turn freely but do not turn the contact coil (on the combi-
nation switch) more than allowable number of turns
(about two and a half turns from the center position
clockwise or counterclockwise respectively), or coil will
break.
CAUTION:
Do not hammer the end of the shaft. Hammering it will
loosen the plastic shear pins which maintain the column
length and impair the collapsible design of the column.

STEERING WHEEL AND COLUMN 3C-7
INSTALLATION
1) Check that vehicle’s front tires are at straight-ahead position
and contact coil is centered. Refer to “CENTERING CON-
TACT COIL”.
2) Install steering wheel (1) to steering shaft with 2 lugs (2) on
contact coil fitted in two grooves (3) in the back of steering
wheel and also aligning marks (4) on steering wheel and
steering shaft.
3) Tighten steering shaft nut (1) to specified torque.
Tightening torque
Steering shaft nut (a) : 33 N·m (3.3 kg-m, 24.0 lb-ft)
4) Install driver air bag (inflator) module to steering wheel.
Refer to “DRIVER AIR BAG (INFLATOR) MODULE”.
CENTERING CONTACT COIL
1) Check that vehicle’s wheels (front tires) are set at straight-
ahead position.
2) Check that ignition switch is at “LOCK” position.
3) Turn contact coil counterclockwise slowly with a light force till
contact coil will not turn any further. CAUTION:
These two conditions are prerequisite for installation of
steering wheel. If steering wheel has been installed with-
out these conditions, contact coil will break when steer-
ing wheel is turned.
NOTE:
After installing the steering wheel, turn the steering
wheel about 1 full rotation so that the cancel cam pin fits
into the pin hole in the steering wheel and then check the
turn signal lever for proper function.
NOTE:
Contact coil can turn about 5 turns at maximum, that is, if
it is at the center position, can turn about two and a half
turns both clockwise and counterclockwise.
